摘要
通过研究和系列实验,新建立车用尿素中尿素含量的测定方法(甲醛法)。通过精密度实验、回收率实验和对比实验,证明新建立的测定方法准确可靠。该方法与GB 29518—2013中AUS32尿素含量的测定(总氮法)相比,操作简便、经济实用,节省分析检验成本。
A new method to determine urea content in AdBlue called formaldehyde method was established by a series of study and experiment. The accuracy, recovery rate and comparative experiment proved that the new method was reliable. Compared with GB 29518-2013, AUS32 Determination of Urea Content （Total Nitrogen Method）, the new method is easy to operate, and can save the laboratory cost.
